LIQUID-DISPENSING APPARATUS.

Application filed. October 18, 1823. Serial 110.669381.

Apparatus for delivery of liquids: have become known in which the quantity of liquid delivered is indicated one sea e. The

apparatus of this type-must however beconl trolled by a trustworthy person as otherwise difficulties might arise especiallv whendifierent persons draw off theliquid.

This invention relates to an apparatus for the delivery of liquids. especially benzii'i. the delivery being controlled so that: liquid can be dispensed only whenthe quantity dispensed is automatically recorded at the same time by that counter and recorder which belongs to the person who is using the ap- 16 paratus. P

.-\ccording to the invention a multiple way cock is mounted in the pipe which con muuicates with a reservoir. a measuringvessel and an outflow pipe. a hand lever being, provided for the operation of this cock. This hand lever is locked by a mechanism adapted to be operated by keys. Every time the releasing mechanism is operated with the aid of one of a number of" keys the apparatus is connected with the recorder-which corresponds to the key which has been used. the quantity of liquid which has been tapped dieing recorded accordingly. The invention will be best understood no from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of this FPEPlflCatkHl. with the umlerstauding that while on the drawings one embodiment of the invention is disclosed. the invention is not confined to any strict conformity with the showing of the drawings. but maybe embodied in any manner which does not make a material departure from the salient features of the invention.

In the drawings Fig. 5 shows partly in section and partly Fig. l is a front elevation partly in secin elevation themeasuring vessel with feed pump.

Fig. 10 is a rear elevation of Fig. 1. Fig. 11 shows the bars in elevation. Fig. 12 is a similar view as Fig. 11 showing the bars in difi'erent position.

On a casing 1 a vertical plate 2 is mounted on the upper part. of which the casing of the three-way cock 3 is arranged. The plug 4 of the three cock 3 is keyed on a bolt 5 which traverses the lid 6 and projects from the same. A pine 8 leads. from the tubular socket T to the measuring vessel 9. In the conduit 83a pump 10 is mounted which is adapted to be operated by a hand lover. The vessel 9 consists of a glass cylinder so that the liquid level in the vessel is clearly visible from the outside. In the vessel 9 a standpipe 11 is axially arranged and a return pipe 12 is connected with this standpipe. The vessel 9 is of determined capacity, 10, 20, 25 or more liters. When this capacity has been reached the liquid level is at the upper open end of the standpipe 11 so that all the liquid which is further tilled in flows out through the standpipe 11 and back to the tank through the return pipe 12.

The discharge pipe 14 mounted in the tubular socket 15 may have connected there- 8 is a section through the unwinding 9 shows one of the keys on larger with, as usual. a flexible tube or hose pipe to facilitate the supply of the discharging liquid to motor cars. The feed pipe 8 leading to the benzin tank is mounted on the tubular socket 15.

.1\ disk 16 keyed on a bolt 5 has teeth on its circumference whichare designed to engage with corresponding holes 19 of an endless metal band 18 guided on a disk 20 keyed on shaft .21. The teeth 17 of disks 16 and 2t) engage also with the holes 19 of the metal band 18. I

The shaft 21 is 'ournalled in the. uprights 22. ()n the end of shaft 21 projecting from one of the upri hts 22 a handlever 23 is keyed on the. middle arm of which a wedge shaped projection 24 is arranged. 25 is a stop disk mounted on shaft 21 and having a notch 26 with which the locking pawl 27 engages. This locking pawl 27 is, under the action of a spiral spring 28, pulled a ainst the disk 25. When the locking pawl 2 is in enga ement with notch 26 the sto disk is locke and through the same, sha t 21 and the cock plug 4.

The locking pawl 27 is keyed on the rod 29 which is journalled in the uprights 22. On this rod 29 feelers or pawls 30 are mounted at convenient distances apart the one from the'oth'er, the free "ends of'saidfeelers 30 standing belowv the catches 31 of therods 32. Therods 32 are guidedfin a vertical groove 33 of the transverse bar 34 which-connects the two uprights 2; with one-another and they are maintained by the action of] the spiral springs 35 in the working position. The rods 32 are rig-idly connected with locking bodies 36. The locking bodies 36 have each a diagonal slot 37 with" which engages a stud 38 mounted" on a rotary body 39; These rotary bodies 39 are mounted in a ledge 40 of the transverse bar 34 and carry guide bolts 41 for the keys. On the wall of the casing. sleeves '42, one for each bolt 41. are arranged, The sleeves42 have horizontal slots 42 designed to receive nipples 43 of the keys 44. A vertical groove 45 communicates with the slots 42. When a key is being'inserted and turned its nipple 43 engages with the slot-42? so that the key can be withdrawn only after it has been turned. In this manner it .islprevented'that the key be prematurely removed in order to carry out any forbidden manipulations.

Vhen a key isbeing rotated the corresponding rotary body 39 is rotated also and the stud 38 of the body '39 which slides in the oblique slot 37 of the locking body 36 makes this locking body move down so that the locking rod 32 acts upon the corresponding feeler 30 so that by the rotation of rod 29 the locking pawl 27 is oscillated and comes out of engagement with the locking disk 25. v

The locking rods have at the lower ends two projections 46. 47 (Fig. 7) of which one. 46. carries a figure type 48 indicating the volume corresponding: to the capacity of the vessel 9. for instance 20. .Below the projections 46 a bar 49 is arranged on which the inking ribbon 50 slides. The inking ribbon is endless and guided over pulleys 51. A counter-weighted lever 52 has at one end a roller 53 adapted to roll u on the ink ing ribbon so that it is streiche bythe action of the weight of lever 52 and of the roller 53. The paper strip 54. is guided hotween the printing bar 49 and the inking ribbon 50 and it winds otf spool 55 and on spool 56. A toothed wheel 57 keyed upon.

the axle of spool 55 engages a stud 59 fixed in the fork shaped end of the feed lever 58. This feed lever 58 is oscillatably suspended by means of screw (it) on the projection 47. One of the pulleys 51 is successively rotated by a feeding mechanism analogous to that (56, 58, 59) of the winding up spool.

When the locking rod 32 and its projection 47 descend, the feed lever 58 is lowered and the toothed wheel 57 is revolved by the stud v59 for one unit, whereby the paper stripv 54 is advanced. The spools 55 and 56 are loosely mounted on axles61 journalled in brackets-(i2. The spool 55 has in its inner wall an incision 63 in which a spiral spring (54 is located, This spring bears on the one hand against a screw 64 fixed on the axle and on the other hand on the shoulder formed by the-incision and it exerts a slight brakingaction upon this spool and prevents accidental rotation of said spool.

The locking rods 32' have each a stud 65 in proximity of the locking body 36 said stud extending into the path along which a feed lever'66 of the counters 67 moves. The counters .67 are (30111 osed in the well known manner of figure dis s, viz, one for the units, one for the tens, one for the hundreds and one for the thousands. At each downward os .-illation of a feed lever 66 caused by the locking rod 32a feeding forone unit is produced by means of the studs 65, the unit corresponding with the volume (10, 20, 25 liters) of the vessel 9. The feed lever 66 controlledby a spiral spring 68 so that after it has been released by the stud 65. it

returns always to its normal position. The counters 67 are enclosed in a casing 69 which has for each counter one window 70 and is locked by a lock not shown in the drawing.

On the middle arm of each locking rod 32, a bolt 71 is arranged which in the normal position stand-s over the inclined slits 72 of a rail 73. A secondbar 7 5 isin contact with rail 73 and has indentations 76 which form eacha. barbed book 77. The bars 73 and have a slit 74 near each end which slits are traversed each by a screw 78 in the transverse bar 34. A stud 79 on bar 75 is connected by a helical contractile spring with one of t e screws 78. The bar 75 tends permanently to move to the left (F 12 under the action of the spiral sprin 80. en the locking rod 32 descends, the It 71 slides in the slit 77 and in the indentation 76 wher y the two bars are moved to the ri ht (Figs. 11 and 12). When the bolt 71 is in the lowest position registering with the barbed book 77 and bar 75 is moved to the left by the action of the spiral spring 80 Fig. 12 so that the stud is locked by the bar 1 hoo 77. In

.this position the locking rod 32 is prevented from being raised.

The bar 75 has further a bolt 81 projecting 2% into the vessel 9. The cock 85 from one of the uprights and carrying a dro pawl 82 adapted to oscillate from the horizontal position upward. This pawl 82 is ac ed upon by a torsion spring 83 fixed by means of screw 84 on one of the uprights 22 designed to maintain the pawl in the horizontal position.

An angle piece 88 on the top plate of the vessel 9 carries a valve in order to prevent pressure above the normal which might be produced by thermic influences. A shutting ofi cock 85 is mounted in the conduit 8 in front of pump 18.

The keys 44.- have each a bit or bits 86 designed to engage with corresponding indentations of the rotar bodies. Each rotary body can therefore e operated only by its own key.

The operation of the apparatus is as follows?- The cock lug 4 is normally in such a position that the conduit 8 communicates with conduit 8 so that at the pumping, the liquid from the tank flows through the conduits 8, in conduit 8 must evidently be open. If the level of the liquid arrives at the upper end of the standpipe 11, through which liquid in excess will flow out, the pumping is stopped. In oro'er to tap oil" the licnzin or other liquid the plug 4 must be turned so that the con- Cult 8 is in communication with the pipe 14. "With this object in view a kc is put on the guide bolt 41 and turned in clockwise direction approximately for one quarter revolution. The lockin body 36 makes the looking rod 32 descent? by means of stud 38. The stud strikin upon the feed lever 66 the counter 67 is advanced accordingly. At the same time the type 48 at the lower end of the rod 32 is printed and records the quantity of benzin which is delivered.

The bolt 71 engaging with slit 72 and identation 76 produces. owing to its downward movement in vertical direction, a displacement of the two bars 73, 7 5 towards the right (Figs. 11 and 12). The bar jumps back through the action of the spiral spring 80 as soon as bolt 71 passes below the barbed hook 7 7 so that it is locked. In this position of bar 75 bolt 71 and the locking rod 32 cannot move upward. It is also impossible to remove the key 44 as its nipple 43 engaging with slot 42 prevents this.

The projection 31 strikes at the same time upon the feeler 30 and efi'ects a rotation of rod 29 wherefrom results an oscillation of the locking pawl 27 so that it comes out of engagement with the indentation 26 of disk 25. The shaft 21 and consequently disk 20 are now free to be rotated so that disk 16, bolt 5 and the cock plug 4 are rotated also.

The rotation of shaft 21 is effected by the hand-lever 23 which swings from its normal position (dash line in Fig. 6) in upward direction into the position (mixed line). At this oscillation of the hand lever 23 the cock plug 4 is adjust d o that the conduit a made to connnnnicate with the tube 14 mounted on the l.. ll1l3l3l socket 13 so that benzin can flow out f the vessel 9.

It is impossible to operate the as the cock plug has been adjusted that the connection of the Feed pins 8 tubular socket 5 with the 8 int i In order to wl is lowered so i on pawl and bolt 81 in inwa T3 is moved to displacement if is released by th corresponding the action of upper normal p ll; respectively which stud 38 and with the f to their initial W withdrawn.
